Copernicus: A Scalable, High-Performance Semantic File System

Abstract

Hierarchical file systems do not effectively meet the needs of users
at the petabyte-scale. Users need dynamic, search-based file access in
order to properly manage and use their growing sea of data. This paper
presents the design of Copernicus, a new scalable, semantic file
system that provides a searchable namespace for billions of
files. Instead of augmenting a traditional file system with a
search index, Copernicus uses a dynamic, graph-based file system
design that indexes file attributes and relationships to provide
scalable search and navigation of files.
